ICE KEBFIIN'G OB SCORING MACHINE.

Application filed January 19. 1922. Serial No. 580,888.

To all whom it may Be it known that I, THEODORE A. Sammie- HUHN, acitizen of the United States, residing at Canton, in the county of Starkand State of Ohio, have invented'a new and useful Ice Kerfing or Scoring.Machine, of which the following is a specification.

This invention relates to ice kerfing machines especially adapted forkerfing or scoring large blocks of artificial ice in order that the samemay be easily separated into smaller blocks of predetermine size.

The objects of the invention are to provide a machine of this characteradapted to receive the blocks of ice in the standing 0- sition inwhich.they are usually, hand ed upon the floor and to place the sameupon the machine in a fiat position, means being rovided forcontinuously carrying the block of ice through the machine and kerfingthe same longitudinally and transversely upon the upper and lower fiatsides.

Other objects are to rovide a machine of this character which 1s compactand entirely above the floor, occupyinga minimum amount of floor space,bein only sufiiciently high to provide means for erfing the uppersurface of the blocks of ice and to provide a single driving means forall of the mechanism.

The above and other objects may be attained by providing a machine asillustrated in the accompanying drawings, in which means are providedfor receiving the cakes of ice in an upright position and depositingthem upon a conveyer in a flat position, means being rovided for kerfingthe upper and lower si es of the cake as it is carried through themachine upon the conveyer, means being provided at the delivery end ofthe conveyer for delivering the ice upon a second conveyer traveling atright angles to the first conveyer, kerfing means being located adjacentto the second conveyer for kerfing the upper and lower sides ofthe blockof ice at right angles to the kerfs first provided therein, the block ofice being deivered' from the machine and deposited u on the floor in theupright position as be ore placing onthe machine.

The invention thus set forth in general terms is illustrated in theaccompanying drawings, in which- Figure 1 is a plan view of a machineembodying the invention, the upper portion each of the machine beingremoved for the purpose of illustration;

Fig. 5, a section on the line-55, Fig. 1; and i Fig. 6, a section on theline 6-6, Fig. 5.

- Similar numerals of reference indicate corresponding parts throughoutthe drawings.

The usual block of artificial ice is proportioned as illustrated in thedrawings, being comparatively narrow and for the'purpose of conveniencein handling, the, blocks are generally placed in an upright positionupon the floor in order that they may be easily slid over the floor ofthe ice house.

The machine embodying this invention is designed to-receive the blocksof ice in this upright position and deposit them upon the conveyer in aflat position in which osition they are carried through the machine,being kerfed both longitudinally and transversely upon the upper andlower flat sides and delivered from the machine in an upright positionupon the floor.

Referring to the construction illustrated in the drawin s, the entiremachine is car ried upon a ase plate 1 which may be formed of one ormore sections, as desired, and which is mounted directly upon the floorand entirely above-floor level. At the loading end of the machine isprovided a tiltingl frame comprising a pair of arms 2,

aving the depending, outwardly inclined portion 3 terminating in thehorizontal portion 4, these arms being spaced and mounted upon therockin shaft 5.

. Suitable bearings 6 an 7 are provided for the shaft 5, the bearing 6being carried by the end frame 8 which is spaced from the adjacent endof the base plate, the bearing 7 being carried b a similar frame 8'located adjacent to the ase plate, a gear segment 9 is fixed upon theshaft 5 and meshes with a similar segment 10 mounted upon the shaft 11which is journaled in bearings 12 carried by .the frames 8 and 8 andwhich extends to the forward end of the machine whereit is journaled inthe bearin s 13 carried. u on the frame members 14, upli-. cates oframes 8, located at the otherside of the base plate.

Each of said rodsis provided at its outerextremity with a rack portion 66 meshing with the adjacent pinion 67,said pinions being mounted upon shorter shaft 68 carried in the bearings69, said pinions meshing with the gear segments 70 fixed upon the shaft11.

A shaft 71 is located at rightangles to the rollers 17 and journaled intakeup stands carrying adjustable bearings 72 the take-up stand beinglocated upon theadjacent portion of thebase plate. Sprockets 73 arelocated near opposite ends of the shaft 71 and are connected by means ofthe conveyer chains 74 with similar sprockets 75 fixed upon the shaft 76which is journaled in bearings 77 fixed upon the base plate. The chains74 are of the same construction as the chains 34, being provided withthe wooden blocks 78.

The shaft 76 extends inwardl and vis connected to the worm wheel sha t79 located in the housing 80 and provided with the worm wheel 81 whichmeshes with the worm 82 fixed upon the shaft 83 journaled in suitablebearings'84 and 85 carried upon the base plate.

The shaft 83 is connected as by the silent drive chain 86 with the shaft87 journaled in bearings 88 and 89, mounted upon the base plate. A.sprocket or gear 90 is carried by the shaft 87 and is connected as bythe silent drive chain 91 or gearing with the sprocket or gear 92mounted upon the shaft of the motor 93' which is located upon the baseplate. A bevel pinion 94 upon the shaft 87 meshes with the-pinion 49upon the shaft 46.

Standards 95, similar to the standards 50, are mounted upon the baseplate upon opsite sides of the conveyer chains 74. l Bearin 96 arecarried in the lower portions 0 these standards and journaled therein isa shaft 97 provided at its inner extremity with a bevel pinion- 98meshing with the pinion 99 upon the shaft 87. Circular saws 100 areadjustably mounted upon the shaft 97 and arranged to cut transversekerfs in the under surface of the block of ice as indicated at C in 'Fi2. Y

The shaft 97 is provide at its outer end with a bevel pinion 101 meshingwith a pinion 102 upon the vertical shaft 103, said shaft beingjournaled in bearings 10% mounted upon the adjacent standard 95. A.bevel pinion 105 is fixed at the upper end of the shaft103 and mesheswith the pinion 100 upon the saw shaft 107 which is journaled inbearings 108 providedin the capped portions of the standards 95.Circular saws 109 are adjustablyvmounted upon the shaft 107 and arran edto cut transverse kerfs in the up er sur ace of the block of ice shownat C in ig. 2.

The 0 eration of the machine is as follows: re erring to Fig. 3, a blockof ice as indicated at A is placed upon the rocking frame 4 in anupright POSltIOII; This frame being located close to the floor, it willbe seen that the block may; be easily placed thereon in this position,as it is customary to handle the block in an upright position upon thefloor.

The frame 4' is then rocked upon the shaft 5 by means of the lever 24:,the arms 18 being thus raised at'their free ends and the block of ice isreceived thereon from the frame 4, the block being deposited upon thearms 18 in the flat position. The stops 20 will be engaged by the blockas it is slid upon thelnclined arms. 18 and when the lever 24 isreturned to the normal position, the arms 18 will be lowered totheposition shown in Fig. 3, and the block will rest thereon in theposition shown at B in Fig. 3.

As the arms 18 are lowered to the normal position, the block B will restupon the rollers 16 as best shown in Fig. 2, the forward end of theblock bein in proximity to the conveyer 34. The bloc of ice may beeasily moved forward upon the rollers 16 until the forward portionthereof is engaged by the conveyer 34, the wood-en blocks 35 thereonfrictionallfy engaging the under sur face of the block 0 cc and carryingthe same forwardly through the machine and between the saws 55 and 55,kerfing the block of ice longitudinally to a depth of about two andone-half or three inches.

The block of ice will be deposited upon the rollers 17 as it passes fromthe conveyer 34 and will be stopped by engagement with the guide 111,assuming the position indicated at C in Figs. 2 and 5.

As each new block of ice is placed upon the receiving end of themachine, the operation of the rocking frame 4 will, through the shaft 11and the pinion and segment bestillustrated in Fig. 5, move the pusherrods 63 in the direction of the arrow upon Fig. 5,

severing into smaller blocks by the use of' the usual ice hatchet orpick without danger of splitting in uneven sizes.

It will be understood, of course, that any desired arrangement of sawsmay be provided for kerfing the blocks of ice at different places uponthe surfaces thereof in order to cut the same into various sizes ofsmaller blocks.
